Title:
METHOD AND DEVICE FOR INFORMATION RECOMMENDATION
Document Type and Number:
WIPO Patent Application WO/2020/233432
Kind Code:
A1
Abstract:
A method and device for information recommendation. The method comprises: acquiring user behavior data and processing the acquired user behavior data to obtain user attribute information and user behavior feedback information (100); updating a parameter item and a non-parameter item of an evaluation model on the basis of the user behavior feedback information of a user with respect to a recommended candidate item, and generating, on the basis of the user attribute information and of the user behavior feedback information, user characteristic information expressing a user preference (101); when making an information recommendation to the user once again, evaluating, on the basis of the updated evaluation model and of the user characteristic information, each candidate item in a candidate dataset to be recommended, recommending a candidate item on the basis of the evaluation result, and returning to step 101. The method combines the advantages of a parameter model and of a non-parameter model, implements fast convergence, and ensures a shortened theoretical loss distance from an optimal solution, thus ensuring that a recommended result is of increased quality, and enhancing user experience.
